3Claims.

The invention relates to a liquid container, as described in the present specification and illustrated in the accompanying drawing which forms features of construction pointed out broadly andy specifically in the claims for novelty following a description containing an explanation in detail of an acceptable form of the invention.

The objects `oi? the invention are to devise a container that will be made of stiff cardboard or other pulp material that will be so constructed as to withstand great pressure and be especially adapted to contain milk or such like fluids which maybe easily poured from the container; to supply a container of a shape that can be 'easily handled, of neat appearance, cheap to manufacture in comparison with a glass container; and generally to provide a container that will be 20 sanitary, simple to manufacture, durable in use and eflicient for the purpose described.

In the drawing, Figure 1 is a front elevational view of the container.`

Figure 2 is a plan view of the top of the container.

Figure 3 is` an enlarged fragmentary vertical section taken on lines 3--3 in Figure 1.

Figure 4 is an enlarged cross section taken on ,lines 4-4 in Figure 1.

Figure 5 is an enlarged vertical section through the wall of the container taken on lines 5-5 in Figure 3.

Figure 6 is a fragmentary side elevation of the container with the plies of paper broken away `to show the wall construction.

Figure 7 is a plan view of the top of the container showing the spout in its pouring position.

Like numerals of reference indicate corresponding parts in the various figures.

Referring `to the drawing, the container, being square shaped has the sides l0, 11, 12 and 13 and is closed in by the top 15 and the bottom 16.

'I'he sides are arc shaped, the purpose of which will be hereinafter more particularly described and merge into the rounded corners 17 giving the container a neat appearance and addedv strength.

The side walls are comprised of layers of cardi (CL 22S-4.5)

ing rigidly fastened together by any well (means, such as cement or glue.

The top 15 having the downwardly extending ange 21 is securely fastened between the outer layer 18 and the inner layer 19 and is fastened into 5 position when the side walls are made, and` secured in place to make a tight joint.

'I'he side walls are rolled in at the bottom as at 22 and are adapted to engage the flange 23 of the bottom 16 and hold it rigidly in position. l0 The sight gauge 24 is situated in the side wall near the top and serves to show the consumer how much liquid is in the container and also in the case of handling milk, it shows the cream line.

'Ihe slot is sealed on the outside and inside by strips 25 and 26 of any transparent substance,

`such as mica, or cellophane. Situated on the top 15 adjacent to one of the rounded corners is the seal cap 27 and the folding spout 28. The fold- 20 ing spout 28 in its closed position completely covers the seal cap 27 and is sprayed with parafiln to hold it in its down position when the container is filled.

'Ihe inner layer 19 has the reinforcing ribs 33, g5 34, 35 and 36. 'Ihese ribs are formed by means of a slot on the mandrel upon which the carton is formed, the inner layer 19 simply being crimped inwardly providing a rib the depth of the container and abutting the bottom 16. As 30 many reinforcing ribs as necessary in various constructions may be used, of course, but for the purpose of illustration, four are shown.

The side walls being one continuous strip and the top ange having to be inserted between the 35 two layers, it is necessary to simply nick the edge of the strip in order to insert the flange 21 of the top l5.

When it is desired to open the container the spout is raised at its free end 28, the other end 29 40 being rigidly held to the top 15 by means of a staple fastener 30, and folded upwardly and outwardly, this releases the wing portions 3l and 32 which ordinarily are folded under and when pouring these form the side walls for the spout s which greatly facilitates the pouring of the liquid.

This novel `spout thusly forms a double seal, creating a much more sanitary condition in handling liquids of this kind, and also owing to the fractional cost of this container, compared to one of glass, the container may be used once only by the consumer, then destroyed, thusly ensuring Ithe user of a sanitary container hermetically sealed and efficient for the purpose set forth. 55

comprising an inner seal member and a. folding spout member suitably secured to said top and forming en integral part thereof. t

3. In a liquid container, a roll of paper board including fabric insert between the rolls for strengthening the walls, reinforcing ribs formed by the inner wall extending between the top and bottom of said container and adapted to form a shoulder .n connection with the bottom of the container and the sealing means.
